❖Communication practices: Principle 1 Listen: •Try to focus on the speaker‘s words, rather than formulating your response to those words. •Ask for clarification if something is unclear, but avoid constant interruptions. •Never become contentious in your words or actions (e.g., rolling your eyes or shaking your head) as a person is talking. Principle 2 Prepare before you communicate: •Spend the time to understand the problem before you meet with others. If necessary, perform some research to understand business domain. •If you have responsibility for conducting a meeting, prepare an agenda in advance of the meeting. Principle 3 someone should facilitate the activity: •Every communication meeting should have a leader (a facilitator) 1)To keep the conversation moving in a productive direction, 2)To mediate any conflict that does occur, and 3)To ensure that other principles are followed. Principle 4 Face-to-face communication is best: •It usually works better when some other represen...
What is Java Virtual Machine and Command Line Arguments
Java Virtual Machine
All language compiler translate source code into machine code for a specific computer .Java compiler also does the same thing ,Then how does java archive architecture neutrality ? The answer is that the java compiler produces an intermedia code known an bytecode for a machine that does not exits , This is a machine is called the java virtual machine and it exits only inside the computer memory , It is a simulated computer within the computer and does all major machine of a real computer, illustrates the process of compiling a java program into byte code which is also referred to as virtual machine code
The virtual ma chine code is not machine specific code (known as machine code) is generated by the code interpreter by acting as an intermediary between the virtual machine and the real machine as shown in Remember that the interpreter is different for different machines.

Illustrate hoe java work on a typical computer , The java object framework (Java API) acts as the intermediate between the user the virtual machine which in turn acts the intermediary between the operating system and the java object framework
.Command Line Arguments
There may be occasions when we may like our program to acts in a particular way depending on the input provided at the time of in the executions . This is archived in java program by using what are the known as command line argument , command line argument are para meter that are supplied to the application program at the time of invoking it of execution , It may be recalled that program was for invoked execution of the command line
.Here, we have not supplied any command line argument. Even if we supply argument, the program does not know what to do with them.
We can write Java programs that can receive and use the argument provided in the command line. Recall the signature of the main ( ) method used in our earlier example programs:
As pointed out earlier, is declared as any array of string known as string objects .Any argument provided in the command line at the time of execution are passed to the array its elements , We can simply access the array element and use them in the program as we wish .

What is Software process framework And, Umbrella activities
❖ Software generic process framework activities . A process framework establishes the foundation for a complete software process by identifying a small number of framework activities that are applicable to all software projects, regardless of their size or complexity. • In fig each framework activity is populated by a set of software engineering actions. A collection of related tasks that produces a major software engineering work product. • Each action in process framework is populated with individual work tasks that accomplish some part of the work implied by the action. 1. Communication: Communication framework activity involves heavy communication and collaboration with the customer,encompasses requirements gathering, data gathering and other related activities. 2. Planning: Planning activity establishes a plan for software engineering work that follows. Planning describes the technical tasks to be conducted, the resources that will be required, schedule, and the risks...
What is Constants, Variables, and Data Types
Constants Constants in java refer to fixed values do not change during the execution of a program , Java support several types of constants as illustrated. .Integer Constants An integer constant refer to a sequence of digits , There are three types integers .namely decimal imager octal integers and hexadecimals integers . Decimal integers consist of a set of thing preceded by an optional minus sign Valid of decimals integer constant .Variables A variable is an identifier that denotes a storage location seed to store a data value unlike constant that remain unchanged during the execution of a program , a variable may take different values at different times during the execution of the program ,we had used several variable for instance , we used variables length and breath to store the values o...
What is DDL --Data Definition language and DML -Data manipulation language
DDL --Data Definition language DML -Data manipulation language DDL --Data Definition language:- To create alter drop the table in or database we use data Definition language. The DDL command is used to built or modify the structure of a database or a object in that for the database object are any data that store and create in database For-tables, Rows and View 1.Create Command 2.Alter Command 3.Drop Command 4.Rename Command 1.Create Command:- To create database objects like table or modify database we used create command, The create statement is use to the create any types of objects. Syntax-Create table table name (column 1 data type (size), Column 2 datatype (size) ). Create table students (Id int , name varchar (255)); To view the create structure we use describe command " describe the table name. 2.Alter Command:- One there table or database create we required to change a structure of the database or class object we use into the alter comm...
